Whether it's in real life or in fiction, one saying indeed holds true: True love knows no boundaries. In the world of fiction alone, I've witnessed scenes of that sort quite a handful of times. Given the main characters of this manga, it somehow reminded me of Chobits, which featured a human male and a gynoid robot (Persocom, to be precise), with a few differences that made it a masterpiece in my opinion.

Story-wise, Believe Machine introduces us to the life of twenty-year-old Masaru Yoneda and the gynoid robot Yuu (No. U-910710, Prototype Unit 2). What seemed bad luck for Masaru at the start of the
story turned good upon his encounter with the inactive Yuu. As with any other romantic story, trials are sure to try to separate them from each other, including a big one that tests Masaru's heart and his love for Yuu. Eventually, the ending and short epilogue were truly heartwarming and touching, to the point that I almost got misty eyes. Hence, a caveat for fellow guys planning to read this hentai manga: Have more than just one box of tissues by your side. You never know when you'll be 'shedding manly tears' on this.

Artwork is satisfactory. Even though I was reading it in original Japanese language, where my knowledge of the language is still fragmented, I'd still find myself understanding the plot, since the main characters' emotions were well-depicted.

In terms of character development, Ozaken did a splendid job on this work. In just four chapters, Masaru has moved on in life after his breakup, and showed that he can love somebody once more. Even if that girl was Yuu, who happened to be a gynoid robot, constructed with the most sophisticated technology. If robots of her kind were to be constructed in the real world, calling such accomplishment as a milestone in the scientific community would still probably an understatement.

Honestly, I never thought I'd be encountering this manga series when I was browsing on Fakku!, probably the best-known hentai manga website. And I'm thankful that I got to read this work. Sexual content or no sexual content, works like this are really rare to come by. Sure, I loved CLAMP's Chobits, but Believe Machine, despite being shorter than the former, has surpassed it in terms of plot and character development. Since this is a manga with adult content, this is something I'd recommend with caution, though.

Bottom line: Who says hentai-genred works of fiction can't have a storyline as good as Believe Machine's?
